5. Connection

The installation shall be done by qualified installation personnel and should conform to all national
Important
and local codes.
DANGER
• Make sure to turn off the switches of this product and the distribution box before starting connections.
• Do not perform any connection work with moistened hands.
• Make sure to insulate all bare current-carrying parts like joints and so on by tape, etc.
• Do not strain cables, or let them make contact with the welding arc area.
• For safety reasons, make sure to provide this product and base material with class D or class C grounding
work done by qualified electricians.
CAUTION

5.1 Connecting output cables

This section explains the connection in case of using a
special torch. (The same applies to connections for the arc spot.)

Note: Insert it into the "(-)/(+) terminal" in line with the guide respectively,
and turn it clockwise until it is locked.

5.1.1 About output cables (Below figures are images)

Lay the torch cable and base-material-side cable side by
side without winding to keep down their impedance (alter-
nating current resistance in the circuit)
If it is necessary to wide the cables:
• Wind the torch-side cable and the base-material-side
cable respectively in opposite directions.
• Wind in the same winding number.
• Wind each of the winding piled alternately.
Note
Large impedance may cause Err-13 (secondary over-
voltage error. See section "Troubleshooting".)
OMCTT5639E09
Touching current carrying parts may cause a fatal accident like an electric
shock, burn injury and so on. To prevent physical accidents like an electric
shock, burn injury and so on, make sure to observe the followings.
Observe the followings to prevent a fire caused by overheat of cables.
• Use cables at least with specified thickness.
• Fasten all cable connections securely.
